The wider they are, the less they'll cut into the corners of your timbers, at least softwood. We have 2 sets of 4" x 14' "eye-eye" slings that we use with a crane on site. We also have a big bin of 2" "endless" slings of various lengths that come with to raisings. You just never know what you're goign to need.

I custom order my slings from Hunter Slings:
